Modify theme templates to show the description on the chosen position and not only "on hover"

Summary

In the CERN Theme when using the description field in a webform, the description appears on hover. This behavior is inherited from the Bootstrap theme. Modify the theme template to show the description in the position selected by the user.

Possible fixes

The default Drupal behavior is set by Classy template: https://git.drupalcode.org/project/drupal/-/blob/8.8.x/core/themes/classy/templates/form/form-element.html.twig

However Bootstrap theme overrides this template. https://git.drupalcode.org/project/bootstrap/-/blob/8.x-4.x/templates/input/form-element.html.twig

The issue can be resolved if the CERN theme re-overrides the Bootstrap template.
